| titleOfInvention | Method for reducing curing temperature of butylated hydroxytoluene propellant and butylated hydroxytoluene propellant |
| abstract | The invention relates to a method for reducing the curing temperature of a butylated hydroxytoluene propellant and the butylated hydroxytoluene propellant, wherein a certain amount of high-efficiency bismuth curing catalyst is added into the butylated hydroxytoluene propellant taking TMXDI as a curing agent, and specific components and optimized using amount of the high-efficiency bismuth curing catalyst are given, so that the curing temperature of the butylated hydroxytoluene propellant taking TMXDI as the curing agent can be reduced to 50 ℃ from 70 ℃ when a common curing catalyst triphenyl bismuth TPB is used, and the thermal stress and the curing cost in the curing and cooling process are obviously reduced; in addition, the invention provides the hydroxyl terminated polybutadiene HTPB serving as an adhesive, TMXDI serving as a curing agent and a high-efficiency bismuth substance serving as a curing catalyst, the curing temperature of the propellant with TMXDI serving as the curing agent is obviously reduced through the optimized design of all components and contents in the hydroxyl terminated polybutadiene HTPB, the temperature difference between the curing temperature and the working temperature of an engine is reduced, the thermal stress of the propellant in the curing and cooling process is reduced, and meanwhile, the propellant still maintains excellent mechanical property and aging property. |
